To avoid shading other crops, I would like to grow my Jerusalem artichokes permanently in the same row at the northern end of my allotment. Will there be problems over time with plant health and nutrient depletion of the soil?
Artichokes tend to grow in same place year after year - often because they regrow from pieces left in the soil. There is always a risk of disease, and ideally we would suggest a three-year rotation. However, many allotment sites have Jerusalem artichokes growing successfully as permanent windbreaks. You could try a permanent site, but be prepared to move it if the plants do not thrive.
